+# What's new in babel 3.86
+
+(Draft)
+
+## Revised `tabular` and new layout option `notabular`
+
+While all-RTL or all-LTR `tabular`s are more or less straightforward, a
+tabular with ‘mixed’ directions is not trivial, because both the column
+direction and the text one (in the cells) are governed by `\textdir`. A
+new mechanism has been devised, but it have to be necessarily
+incomplete, because cell and table border are not separate
+entities, but part of the cell text.
+
+<s>A new option `layout=notabular` makes no changes (actually, a minimal
+change related to the fact `tabular` is inside a math), so that some
+hacks can be applied. For example, with the `array` package:</s> (syntax
+liable to change):
+```tex
+\newcolumntype{L}{>{\textdir TRT}l}
+\newcolumntype{R}{>{\textdir TRT}r}
+```
